Description

Technical Field

[0001] This utility model relates to the field of gas compression equipment technology, and in particular to a high-efficiency split-flow compressor structure. Background Technology

[0002] In fields such as industrial fluid transportation, power system drive, and refrigeration and air conditioning, compressors, as core fluid compression equipment, directly determine the energy consumption level and operational reliability of the overall system through their operating efficiency, adaptability to operating conditions, and long-term stability. In traditional compressors, the airflow entering the compression chamber directly impacts the impeller, inducing localized eddies. This increases air resistance, causing energy loss, and exacerbates impeller surface wear. Over long-term operation, compression efficiency continuously declines, making it difficult to meet the varying compression demands of different scenarios. Utility Model Content

[0003] To improve the compression efficiency of the compressor, this application provides a high-efficiency split-flow compressor structure.

[0004] The high-efficiency split-type flow compressor structure provided in this application adopts the following technical solution: A high-efficiency split-type flow-guiding compressor structure includes: a duct housing having a flow-guiding space, an air inlet and an air outlet, the air inlet, the flow-guiding space, and the air outlet being sequentially connected; a flow-guiding mechanism including a motor and an impeller, the motor driving the impeller's shaft to rotate, the motor being located outside the duct housing, the impeller being located inside the flow-guiding space, and the impeller's shaft being rotatably connected to the duct housing; and a flow-guiding mechanism including a flow-guiding vane, an adjusting component, and an air inlet housing, the air inlet housing being located at the air inlet and connected to the duct housing, the two ends of the flow-guiding vane being rotatably connected to the inner wall of the air inlet housing, and the adjusting component being detachably connected to the shaft of the flow-guiding vane, the adjusting component being used to change the angle between the flow-guiding vane and the air inlet housing.

[0005] By adopting the above technical solution, the airflow guiding mechanism can flexibly optimize the air intake direction according to actual working conditions by adjusting the angle of the guide vanes. This allows the airflow to enter the guiding space at a better angle, reducing the vortices generated by the airflow impacting the impeller, lowering air resistance, and ultimately improving the overall operating efficiency of the compressor, adapting to the airflow compression requirements in different scenarios. The external motor design avoids the impact of motor heat on the airflow temperature within the guiding space, reducing the decrease in compression efficiency caused by the thermal expansion of the airflow.

[0006] Optionally, the adjustment component includes a rotating rod, the rotating shaft of the guide vane is hollow and has an adjustment space, one end of the rotating rod passes through the air inlet housing and is located in the adjustment space, a first protrusion is provided on the periphery of the rotating rod, and a second protrusion is provided on the periphery of the inner wall of the adjustment space of the guide vane, the first protrusion and the second protrusion cooperate to abut.

[0007] By adopting the above technical solution, the adjustment component is set in the adjustment space by a rotating rod. The first protrusion of the rotating rod and the second protrusion of the guide vane cooperate. When the rotating rod rotates, the first protrusion will contact the second protrusion and push the second protrusion to rotate, so that the guide vane can rotate with the rotating rod, thereby changing the tilt angle of the guide vane.

[0008] Optionally, a positioning component is also included, comprising a base and a positioning pin. The base is connected to the outer wall of the air inlet housing away from the air inlet. The base has an installation space, the rotating rod passes through the installation space, and the positioning pin passes through the base and the rotating rod.

[0009] By adopting the above technical solution, the base and the positioning pin work together to fix the adjusted rotating rod, preventing the rotating rod from shifting due to airflow impact or vibration during compressor operation. The contact between the first and second protrusions also prevents the guide vane from rotating, ensuring a stable tilt angle for the guide vane. The positioning pin passes through the base and the rotating rod, enabling quick locking and unlocking of the rotating rod position, facilitating operation and allowing for rapid adjustment of the guide vane angle according to operating conditions before immediate fixation.

[0010] Optionally, the positioning component further includes a positioning block located within the installation space and sleeved on the rotating rod. The positioning block has multiple positioning channels extending radially through the rotating rod. The multiple positioning channels are centrally symmetrically arranged and interconnected. The positioning pin passes through the positioning channels.

[0011] By adopting the above technical solution, multiple centrally symmetrical and interconnected positioning channels provide multiple sets of fixed positions for the positioning pins, enabling the guide vanes to achieve multi-angle stepped adjustment, adapting to different air intake volumes and different airflow speeds, and expanding the application range of the compressor.

[0012] Optionally, multiple air guiding mechanisms are provided, and the multiple air guiding mechanisms are arranged in parallel at the air inlet with spacing between them.

[0013] By adopting the above technical solution, multiple parallel-spaced airflow guiding mechanisms can separate the airflow into multiple air ducts before entering the airflow guiding space. The number of airflow guiding mechanisms can be flexibly adjusted according to the size of the air inlet and the required air intake volume, further optimizing the air intake efficiency. The tilt angle of the guide vanes in a single airflow guiding structure can also be adjusted individually according to the specific structure of the airflow guiding space.

[0014] Optionally, a drive gear is fitted on the shaft of the guide vane, and two adjacent drive gears are meshed together.

[0015] By adopting the above technical solution, the angle of multiple guide vanes can be adjusted synchronously. All guide vanes maintain a consistent angle during the adjustment process, avoiding airflow disturbance caused by angle deviations of individual guide vanes, ensuring the uniformity of airflow entering the guide space, and eliminating the need to operate each guide vane individually. Simply rotating one of the levers can adjust all connected guide vanes through the drive gear, simplifying the adjustment process, reducing operational complexity, and improving adjustment efficiency when switching operating conditions.

[0016] Optionally, the air guiding mechanism further includes a first gear and a second gear, the first gear being mounted on the output end of the motor, and the second gear being mounted on the shaft of the impeller, with the first gear and the second gear meshing together.

[0017] By adopting the above technical solution, the first gear is set as a large gear and the second gear is set as a small gear. The speed-increasing transmission is achieved through the difference in gear diameters. The speed of the motor output end is amplified according to the gear diameter ratio, which increases the rotational speed of the impeller and the airflow compression intensity. Under the same motor power, higher pressure or greater flow rate of compressed gas can be output, which directly improves the working efficiency of the compressor.

[0018] Optionally, the surface of the guide vane is coated with a wear-resistant coating.

[0019] By adopting the above technical solution, the wear-resistant coating applied to the surface of the air guide vane significantly improves its wear resistance under long-term airflow impact. As the first contact component where airflow enters the compressor, the air guide vane is subjected to the scouring and friction of high-speed airflow over a long period, making it prone to surface wear and affecting airflow guidance. The wear-resistant coating forms a hard protective barrier on the surface of the air guide vane, reducing direct friction between impurities in the airflow and the vane surface, lowering the wear rate, and extending the service life of the air guide vane. Simultaneously, the wear-resistant coating has a low surface roughness, which reduces the frictional resistance between the airflow and the vane surface, further optimizing airflow efficiency.

[0020] In summary, this application includes at least one of the following beneficial effects of a high-efficiency split-flow compressor structure: 1. Through the design of adjustable angle guide vanes, multiple sets of parallel guide mechanisms and synchronously adjustable drive gears, the air intake direction and air duct distribution can be flexibly optimized according to dynamic working conditions such as air intake volume and airflow speed, reducing the eddies and resistance generated by airflow impacting the impeller, ensuring that the airflow enters the compression space evenly and efficiently, and adapting to the compression needs of different scenarios.

[0021] 2. The detachable connection of the adjustment components and the quick locking function of the positioning components simplify the adjustment and maintenance process of the guide vane angle. The wear-resistant coating on the surface of the guide vane reduces component wear, ensures the structural stability of the equipment during long-term operation, and reduces maintenance costs and downtime.

[0031] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail.

[0032] This application discloses a high-efficiency split-flow compressor structure, referring to... Figure 1 and 2 The system includes a duct housing 1, which has an air inlet 102 and an air outlet 103. The duct housing 1 contains a flow guiding space 101, and the air inlet 102, flow guiding space 101, and air outlet 103 are sequentially connected. The duct housing 1 is connected to a flow guiding mechanism 2, which includes a motor 21 and an impeller 22. The impeller 22 is disposed in the flow guiding space 101, and its shaft is rotatably connected to the duct housing 1. The impeller 22 extends through the duct housing 1 to the outside of the flow guiding space 101 and is connected to a second gear 24. The second gear 24 meshes with a first gear 23, which is connected to the output end of the motor 21.

[0033] Reference Figure 2 and 3 It also includes a flow guiding mechanism 3, which includes multiple parallel flow guiding vanes 31, an adjustment component 32, and an air inlet housing 33. The air inlet housing 33 is located at the air inlet 102, with through openings at both ends of the air inlet housing 33, which respectively connect the air inlet 102 and the external space. The flow guiding vanes 31 have a rotating shaft, and the two ends of the rotating shaft of the flow guiding vanes 31 are rotatably connected to the inner sidewall of the air inlet housing 33. The adjustment component 32 is located on the outside of the air inlet housing 33 and is connected to the rotating shaft of the flow guiding vanes 31.

[0034] Reference Figures 4 to 6 The guide vane 31 has a hollow shaft with an adjustment space 3101. The adjustment assembly 32 includes a rotating rod 321 and a knob. One end of the rotating rod 321 is connected to the knob, and the other end passes through the air inlet housing 33 and is located in the adjustment space 3101. A first protrusion 322 is provided on the periphery of the rotating rod 321, and a second protrusion 311 is provided on the periphery of the inner wall of the adjustment space 3101 of the guide vane 31. When the user rotates the rotating rod 321 by holding the knob, the first protrusion 322 rotates in the adjustment space 3101. When the first protrusion 322 abuts against the second protrusion 311, the rotating rod 321 continues to rotate, and the first protrusion 322 pushes the second protrusion 311 to rotate together, causing the guide vane 31 to rotate, thereby changing the tilt angle of the guide vane 31. The tilt angle of the guide vane 31 can be changed according to different air intake and airflow velocity requirements, eliminating local vortices in the air guide space, balancing the overall flow velocity distribution, and improving the uniformity of airflow entering the impeller 22.

[0035] Reference Figure 5 and 6A positioning component 4 is provided on the outer side of the air inlet housing 33. The positioning component 4 includes a base 41, a positioning pin 42, and a positioning block 43. The base 41 is located on the outer side of the air inlet housing 33 and has an installation space 4101 inside. The rotating rod 321 passes through the installation space 4101 and the air inlet housing 33 and extends into the adjustment space 3101. The positioning block 43 is sleeved on the rotating rod 321 and located in the installation space 4101. The positioning block 43 has multiple positioning channels 4301 extending through it in the radial direction of the rotating rod 321. The multiple positioning channels 4301 are centrally symmetrically arranged and interconnected. The positioning pin 42 passes through the side wall of the base 41 and the positioning channels 4301 to fix the rotating rod 321 to the base 41. In this embodiment, four positioning channels 4301 are arranged at equal angles. Of course, in other embodiments, multiple positioning channels 4301 can also be provided. The number of positioning channels 4301 and the angle between the positioning channels 4301 determine the angle at which the rotating rod 321 can rotate with the base 41, which determines the tilt angle that the guide vane 31 can have. The guide vane 31 is rotated by the rotating rod 321, and the rotating rod 321 is fixed to the base 41 by the positioning pin 42. When the guide vane 31 is subjected to airflow impact, since the first protrusion 322 abuts against the second protrusion 311, when the rotating rod 321 is fixed and cannot rotate, the second protrusion 311 is limited by the first protrusion 322, and the guide vane 31 is also fixed and cannot rotate.

[0036] In a preferred embodiment, refer to Figure 4 Each guide vane 31 is connected to an adjustment component 32 and a positioning component 4. The tilt angle of each guide vane 31 can be changed individually through different adjustment components 32, so that the guide mechanism 3 can change the air intake angle at the air inlet 102 according to the actual shape of the guide space 101 in the air duct housing 1 and the gas flow direction, thereby reducing eddy current losses under special working conditions and improving the working efficiency of the compressor.

[0037] In a preferred embodiment, refer to Figure 7 A drive gear 34 is fitted onto the guide vane 31. The drive gears 34 of two adjacent guide vanes 31 are meshed together. One guide vane 31 is equipped with an adjustment component 32 and a positioning component 4. By adjusting the tilt angle of one guide vane 31 through the adjustment component 32, the drive gear 34 rotates with the guide vane 31, thereby changing the tilt angle of the other guide vanes 31. After fixing the angle of one guide vane 31, the tilt angle of the other guide vanes 31 will also be fixed. There is no need to operate each guide vane 31 individually. By simply rotating one rotating rod 321, all connected guide vanes 31 can be adjusted through the drive gear 34, simplifying the adjustment process, reducing operational complexity, and improving adjustment efficiency when switching operating conditions.

[0038] In a preferred embodiment, refer to Figure 8 Multiple guide vanes 31 can be combined to form a guide vane group 31. Multiple guide vane groups 31 are provided on the air inlet housing 33. The drive gears 34 of adjacent guide vanes 31 in a guide vane group 31 mesh with each other. One guide vane 31 in a guide vane group 31 is equipped with an adjustment component 32 and a positioning component 4. The tilt angle of multiple guide vanes 31 in a guide vane group 31 can be changed and fixed by the adjustment component 32 and the positioning component 4. This allows operation of the adjustment component 32 and positioning component 4 for different guide vane groups 31, resulting in different tilt angles for the guide vanes 31 in different guide vane groups 31.

[0039] In a preferred embodiment, the surface of the guide vane 31 is coated with a wear-resistant coating. The wear-resistant coating can form a hard protective barrier on the surface of the guide vane 31, improving the wear resistance of the guide vane 31 under long-term airflow impact environment. At the same time, the wear-resistant coating has a low surface roughness, which can reduce the frictional resistance between the airflow and the surface of the guide vane 31, and improve the aerodynamics of the air intake.

[0040] The above are all preferred embodiments of this application. These embodiments are merely explanations of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape, and principle of this application should be covered within the scope of protection of this application.
